Nashua 330X Extreme Weather Foil Tape [1.75 mil Linered]

Nashua 330X Extreme Weather Foil Tape is an all-weather aluminum foil tape with acrylic pressure sensitive adhesive. It is used to tape joints and seams in duct work for heating, air conditioning, and refrigeration systems. Specifically intended for use over a wide temperature range. Suitable for general repairs and a variety of insulation uses. Also as window mask to protect aircraft canopies, windshields and passenger window surfaces from cracking or hazing during paint stripping. Nashua 330X has a special adhesive system which has aggressive adhesion even at -25°F. Its aluminum foil backing is extremely conformable and its adhesive is quick stick. Low VOC (Volatile Organic Compounds) content and non-solvent for less odor. Contributes toward satisfying LEED EQ Credit 4.1 (Low Emitting Materials).

** Adhesive tape products are NOT guaranteed to be splice-free. Sizes shipped will typically be the tape industry standard metric-cut sizes, i.e. 24mm for each 1 inch of nominal tape width ordered (rolls are approximately 5% narrower than the nominal size). Please contact us to inquire about pricing for full-cut widths; e.g. a 6 inch roll cut to 152mm instead of 144mm.

Offers the widest range of application flexibility available. Exhibits excellent processing performance whether manually or automatically applied. Has superior tensile strength, adhesion properties and holding force which ensures consistent, reliable seals. Hot melt adhesive will bond faster to a surface which is referred to as quick-grab or quick-stick. It typically has higher tack (will feel stickier to the touch), but is also softer. It has lower heat resistance, shear resistance, and sometimes UV resistance than an acrylic adhesive. NOTE: it is called hot melt because the adhesive is applied hot by the manufacturer and then hardens as it cools (you do not need to apply heat to the tape yourself).

natural rubber

Properties are similar to that of hot melt rubber, but natural rubber often holds where other adhesives won't (recycled fibers, dust, cold, heat and heavy loads). It provides good overall adhesion and moisture resistance.

acrylic

Offer excellent performance, especially for applications in temperatures less than 40°F and greater then 120°F. It provides excellent clarity, has high shear strength, is usually more permanent/durable even when exposed to moisture, and it ages well over extended periods in fluorescent and sunlight. Since it remains clear for the life of the application and does not yellow over time it is ideal for applications such as sealing white cartons. While it has good initial adhesion it does take 24-48 hours to cure and to achieve its maximum bond strength (has gradual adhesion buildup). Another difference between hot melt rubber and acrylic adhesive is if you fold tape over making the two adhesive sides touch the acrylic adhesive will remain attached to the carrier (e.g. paper, film) while a hot melt adhesive will stick to itself and pull off of the carrier. It is the best choice for clarity, UV resistance and aging characteristics.

silicone

Is great for extreme temperature applications since silicone adhesive can work in continuous operating temperatures from -100°F to 500°F. They also exhibit good chemical resistance, retain electrical properties, and remove cleanly with little or no residue.

zinc oxide

Zinc oxide based adhesive formula is a skin-friendly adhesive which is commonly used on sports medicine tapes.
